Eike: "Free Pascal" is not a standard Pascal compiler; it violates ISO standards. p2c works fine for me on a Sun computer. It translates from Pascal to C and then one can compile with gcc. One must also compile a library. It works just fine, but is not being developed like gpc. See http://www.lecb.ncifcrf.gov/~toms/delila.html#How.To.Compile for pointers to further information (and source for p2c). p2c and gpc are the only two Pascal compilers that I know about that are real (ISO) and have source available.
